“18yax jajap 女人”南珠高铁玉18yax jajap 女人岑段跨益湛铁路万吨转体梁成功转体

  中新18yax jajap 女人网玉林12月19日电 (18yax jajap 女人韦建松 张召召 莫德钧)12月19日,在广西玉林市容县,南珠高铁玉岑段容西镇跨益湛铁路特大桥超万吨T构转体梁成功转体,标志着该项目建设取得突破性进展。

  由广西交通投资集团有限公司投资建设、国铁南宁局代建的南珠高铁玉岑段容西镇跨益湛铁路特大桥T构转体梁全长161.5米、桥宽12.6米,在15号墩、16号墩处上跨益湛铁路。转体主墩为15号墩,采用墩梁刚性固结形式,转体长度为147米,转体重量为1.09万吨,顺时针38.9,试转体5,正式转体33.9。

  在转体前,南玉铁路公司、南宁铁路工程建设指挥部等相关单位多次到现场检查指导、召开转体专项施工方案研讨会,帮助完善安全穿透式管理体系和监管机制,不仅为项目安全筑牢防线,在技术上也给予大力支持,为推进转体梁顺利转体提供保障。

  在转体操作过程中,现场人员对桥梁进行精确的称重平衡试验,根据多项参数进行配重,调整箱梁至平衡状态。随后,进行了5的转体桥试转,全面检查牵引动力系统、转体体系、位置控制体系以及防倾保险体系的运行状况,并评估了指挥系统的协调性。通过模拟分析、优化张拉牵引力、降低滑道摩擦力等方法,对施工方案进行细致修正,确保每个环节无缝衔接,使整个转体过程一次成功。

  南珠高铁是一条连接广西壮族自治区南宁市与广东省珠三角城市的高速铁路。南珠高铁玉岑段是南珠高铁南玉段的延伸,设计时速为350公里,线路全长111公里。目前,南珠高铁玉岑段路基土石方完成75%、桥梁工程完成83%、隧道工程完成63%。项目预计2026年开通运营,届时玉林与岑溪间铁路通行时间将从70分钟缩短至30分钟左右,有利于进一步改善桂东地区交通条件,密切两地经济联系,推动区域经济一体化。(完)
